/**
* This script creates a temporary file in /tmp named znurt[foo] that sets itself
* to the mtime of the latest package mtime in the database. This way, I can simply
* use find to do all the heavy lifting to quickly locate any package directories
* that were modified since last import.
*
* Directory names in portage tend to get their mtimes updated on a regular basis;
* generally speaking, I'd say that about 50% of them change each sync, though
* I can't pin down why. Packages that haven't been touched in ages get their
* directory modified for no reason I can see.
*
* As a result, the mtime of a package is notoriously unreliable as a reference
* for anything. However, if it does change, it *can* indicate that an ebuild or
* file was removed, so, with all due diligence, we will check those later to see
* if something was actually taken away, and update the database.
*/
/**
* This is the first file where tables start to have a status column. There is
* only three status levels: 0 - completely imported, and "live", 1 - being updated,
* or newly inserted and 2 - flagged to be removed.
*
* The package table only uses 0 and 1. The website should ignore the status, since
* the changes are only to notify the other scripts that something has changed, and to
* look more closely at the files related to the package.
